EXTENSION CURTAIN-ROLLER.

SPECIFICATION forming part of Letters Patent No. 570,720, dated November3, 1896.

A li ti fil d March 27, 1896. Serial No. 585,09l. (No model.)

T 0 all whom it may concern:

Be it known that LANSEL F. TEMPLE, a citizen of the United States,residing at Muskegon, in the county of Muskegon and State of Michigan,have invented certain new and useful Improvements in ExtensionCurtain-Rollers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has reference to certain new and useful improvements incurtain-rollers of the variety commonly denominated adj ustable orextension rollers.

The object of the invention is to promote cheapness in the manufactureof such rollers as well as to insure the same stifiness and durabilitypossessed by a roller constructed out of asingle integral piece ofmaterial. Various attempts have heretofore been made to provide anextension-roller by the use of which the roller could be adjusted to anydesired length and when so adjusted might be positioned in thewindow-frame and serve as well as if it were made of a single piece ofmaterial, yet eiforts heretofore made in this direc- My invention aimsto make more perfect the construction of rollers of this class.

It therefore consists, essentially, in the construction, arrangement,and combination of parts substantially as will be hereinafter described, and then more particularly pointed out in the claims.

In the accompanying drawings, illustrating my invention, Figure 1 is aside elevation of my improved extension-roller. Fig. 2 is a transversesection on the line 2 2 of Fig. 3. Fig. 3 is a longitudinal sectionalview on the line 3 3 of Fig. 4. Fig. 4 is a transverse section on theline 4 4 of Fig. 3. Fig. 5 is a perspective view showing in detail thecontiguous end portions of the roller-sections and also the Z-shapedmetallic connecting-strip. Fig. 6 is a detail plan view of therectangular metallic blank out of which the Z-shaped connecting-strip isbent.

Similar letters of reference designate corresponding parts throughoutthe difierent figures of the drawings.

In carrying my invention into practical effeet I first provide twosections or pieces, both of which are rolls and of substantially equaldiameter, but, if desired, diifering in length, one being comparativelylong and the other comparatively short, although it is obvious that therelative lengths of the two parts are unimportant.

V A and B designate examples of the two cylindrical pieces of woodemployed together to constitute in conjunction with the connecting-stripmy improved roller of the kind referred to, A being the longer piece andB the shorter piece, for example, although it makes no difierence whatthe relative lengths of the two pieces are. Both of these pieces A and Bare slotted at their contiguous ends with longitudinal central slots cutdiametrically through the pieces and running from the contiguous endsfor a certain desired distance through the roller-sections, the sectionA having the slot a, and the section B having the slot In order toconnect the two roller-sections A and B together, I employ a Z-shapedmetallic connection,preferably made out of a single thin sheet of tin orother suitable material, as shown in Fig. 6. This tin blank is bent intothe form shown in Fig. 5, where it is observed that the Z-shapedconnection consists of a central part C of proper size to easilyaccommodate itself within the slots at and b in the roller-sections Aand B, and said central part 0 having the reversely-bent portions 0 O,which are curved sufficiently to enable them to easily overlap andembrace the portions of the periphery of the roller-sections with whichthey come in contact. edges of the curved portions O C of the Z- shapedconnection are inturned to form The outer flanges c c, which flanges aredesigned to en gage the external peripheral longitudinal grooves a a,which are cut in the roller-sec= tion A, and the grooves b b, which arecut in the roller-section B.

In assembling together the several parts just described it will bemanifest that the Z shaped connection will be placed with its centralportion (J within the slots a and 1), its curved portions 0 Goverlapping the exter* nal surface of the sections A and B, and its toointurned edge flanges c c entering the grooves a and b, all as clearlyshown in Fig. 1, and that when the parts are in this position theroller-sections A and B may be adjusted toward or away from each otherand the resulting completed roller made of the desired length.

The Z-shaped connection is preferably provided with a central slot D,which terminates a short distance from each end, and the central portion0 of the Z-shaped connection is corrugated, as shown, the corrugationbeing for the purpose of strengthening this part of the connection andmaking it much stiffer than it otherwise would be. lVhen the slots atand b are cut in the sectionsAand B,enough material is taken out by thesaw cut to give to the sections a certain amount of spring action. Nowthe corrugated central portion of the tin connection is a little thickerthan the saw cuts, and when it is introduced thereinto, as shown inFigs. 2 and. 4,-the result is to spring the wooden pieces outward to acertain extent, and thus the flanges 0 care held more firmly in theslots into which they fit.

One end of the Z-shaped connection is fas-- 3 and 4,) which is driventhrough one or the other of the roller-sections A or B, as the case maybe, and which prevents the rollers from beingpulled apart and thuslimits the extensibility of the roller.

Various changes in the precise shape, construction, size, andarrangement of the Various parts may be made without. departing from myinvention, and I reserve the liberty bination with the sections havinglongitudi nal, diametrical slots,of the Z-shaped metallic connectioninserted into said slots, said connection having overlappingreversely-bent curved edges which externally engage the sections.

2. An extension-roller, consisting of a pair of sections, audanintermediate Z-shaped metallic connecting-strip having a centralcorrugated portion and overlapping curved and flanged parts whichengageslots in the external surface of the roller-sections, sub

stan-tially as described.

3-. An extension-roller, consisting of the roller-sections havinglongitudinal slots, and

a Z-shapedcorrugated connection inserted within said slots and havingoverlapping flanged portions that engage grooves in the roller-sections.

4.. Air extension-roller, consisting of the and the reversely bentcurved overlapping portions that embrace the external face of theroller-sections, substantially as described;

In testimony whereof I afli-x my signature in presence of two witnesses.
